What is the upper surface of groundwater in an aquifer?

• A. Water Table
• B. Ocean Floor
• C. Aquifers
• D. Desalination

Answer: (A)

Water table is the upper surface of groundwater in an aquifer. It marks the boundary between the saturated zone, where all pore spaces are filled with water, and the unsaturated zone above. The water table can rise or fall with rainfall recharge and groundwater withdrawals, and it generally slopes from higher recharge areas toward discharge points like springs or wells. The other terms don’t describe this surface: the ocean floor is the bottom of the sea, aquifers refer to the groundwater-bearing layers themselves, and desalination is a treatment process for removing salt from seawater.
